The new project, a dish of 13 m diameter, is under way.
Today, 16 Nov 2007, I received the aluminium profiles. Weight 315 kg.
They are safely stored in the garage. Now it's time to make the jig.
The hub and the Honda SuperBlackBird CBR1100XX
I am very concentrated. The jig has to be perfect.
I had to build the jig diagonally in the garage. It's getting tight.
I hope to be ready tomorrow.
28 Nov 2007. The parabolic curve is finished.
17 Dec 2007. My son SM4YEX is checking the parabolic curve.
30 Dec 2007. A new baseline is fixed and the front rib matches the curve. The rear rib is also in the jig.
There will be a breakpoint at 4 m to align the rear rib to the end of the rib.
7 Jan 2008. I'm practicing aluminium MIG-welding, which is difficult and not for amateurs.
23 June 2008. Finally, after a long hold of the construction, I decided to buy a TIG-welder. It works rather smooth but I need some practice.
3 July 2008. I went to a friend and had the parabolic front rib preformed.
The ribs are loaded on the car. I had some problems to see the road.
14 July 2008. The first rib is placed in the jig.
15 July 2008. Today I started welding the rib. I'm not a welder, but after 40 ribs I might be a pro.
16 July 2008. The first rib is completed.
17 July 2008, was a hard working day. Lots of metalwork i.e. cutting all the bracing bits.
23 July 2008. Five ribs are completed.
24 July 2008. I made five ribs which was hard work. Ten made and ten more to go.
28 July 2008. The dish-builder SM4IVE in action.
Rib #14 TIG-welded.
Rib #14 TIG-welded.
30 July 2008. Finally the twenty ribs are completed. Now it's time to start making the twenty shorter ribs.
1 August 2008, I made the first short rib. I decided to use extra ribs instead of aluminium rings. The short rib is 2.76 m.
3 August 2008. Another hard working day. I cut all the material for the short ribs
3 August 2008. I welded five ribs.
9 August 2008. EME conference in Florence, Italy.
SM2BYA,SM5BSZ,SM4IVE,SM7GVF,WA6PY,SM3AKW,SM3JQU
12 August 2008. I made the rest of the short ribs. All ribs are now made and the jig has been disassembled.
17 August 2008 My Grandson inspecting the first rib in the hub.
24 August 2008 at 15.00 Local started to mount the ribbs in the hub
At 21.15 all the ribbs are in the hub. Hard work!!!!!!
30 August 2008 Startded to mount the Rim profile
19 October 2008 mounted the 2 rings at 8 m radius that will hold the short ribbs, as seen in picture.It`s not Aligned it`s just there to see what it looks like.....
4 Januari 2009 snow on dish and -19 Celsius no work could be done
10 April 2009 A new picture of the dish
Dismantled the ring on the tower, now we can plan the future mounting of the dish.
10 May 2009 the tower is UP YEAH

Today 14 January 2012 we did repair the dish structure.
We had a severe storm on 26Dec 2011 (Dagmar) that made some damage to the dish.
I found out that this would be the best solution to reinforce the ribs.So i contacted a prowelder.
We had good weather but -2 deg and windy so it was cold.
